Study Purpose
Update the SO2 emission milestones
for the 309 States
Non-utility source focus
Milestone sources >100 tpy SO2 in
2004 at the facility-level

Methods Summary
Starting point – 2018 SSJF-sponsored
emission projections
MS Excel files posted on SSJF/
projections site
» 2002 emissions
» Growth and control factors
» Equation to estimate 2018 emissions
Revised base year emissions to 2004
values where needed

Methods Summary (Part 2)
Revised SO2 emissions and
algorithms
Consulted with States/sources
Evaluated economic basis for growth
factors
Industry consultations
Revisions made

Revisions Made Since August
1. Chemical Lime Plants (AZ) - revised
base and 2018 SO2 estimates
2. Added Arizona Clean Fuels refinery
to 2018 estimates
3. Refineries (WY)-included EDMS
version 1.3 data in base year - this
revised 2018 values

Findings
Base year data issues
New vs. existing source SO2 rates for nonboilers or FCCUs
Refinery capacity expansion uncertainty
Oil and gas
» Upset emissions importance
» Calibration of activity growth to regional forecasts
» Additional comments on the October report for
this sector (post-2002 control installations)
